Lotus have moved a step closer to using Renault engines in 2011 after their split with Cosworth was made official.

Cosworth issued a statement saying they will no longer supply engines to Lotus as of the end of next month, after the last race of the season:

Cosworth and Lotus have today signed the termination of Lotus Racing?óÔé¼Ôäós engine supply agreement following completion of the deal which was established in principle and announced after the Italian Grand Prix on 12th September 2010. Cosworth?óÔé¼Ôäós support for Lotus Racing will cease at midnight on 30th November 2010.

Lotus Racing has enjoyed a successful season with Cosworth and has enjoyed excellent performance, reliability and support from their engine supply.

The decision to bring the partnership to an early termination has been driven by the team’s desire to solve reliability and performance issues unrelated to the Cosworth engine. Lotus Racing and Cosworth have agreed settlement terms satisfactory to both parties to secure an early termination of the agreement.

Cosworth wishes Lotus Racing success in the future, and will continue to supply engines to AT&T Williams, Virgin Racing and HRT in 2011, thereby supporting 25% of the teams in Formula One.

Yes, I have also been positively surprised. Cosworth has made a giant stride in just one year.
That means that they will be getting better and better. Who knows if they will end up being the best engine of all and have to turn down teams?
I love Cosworth and all the other heritage F1 names.

Cosworth have definitely been one of the many positives this year. Just a shame they were hamstrung by that piece of poorly engineered pants gearbox made by Xtrac! They apparently have big plans for the new engine formula for 2013. Seeing one of their V10’s running at over 20,000RPM on youtube is seriously cool and demonstrates that they certainly know their engines! Also, Cosworth make a fortune out of their military contracts so i would guess that the F1 engine side of things isn’t primarily for profit more a showcase of their skills! Historically when companies do things that way the non profit halo products are superior to the stuff that brings in the cash, for example the Buggati Veyron!

I don’t know whether that is a good dicision if they move to Renault power engine as Red Bull are the quickest car on track cause of their aerodynamics & they are using that high torque of that engine, until they can come up with a good aero based car I don’t think they will profited much.

RBR would do well to have a chat with Cosworth for next year. This years Cosworth engine has been very good and can only be better in the future.Let’s face it, they know what they are doing as they have been building racing engines since the early 60’s !

I don’ want them to go with Cosworth, apart from the fact that the Renault engine have high torque & it is fuel efficient relative to any other engine on the grid one of the best feature of the engine is that it’s very tightly packed which help Newey to play more with the aero of the car.
